2 Network Administration

Note If you want to run more than one job manager on the same machine,

they must all have unique names. Specify the names using ßags with the

startup commands.

Setting the User

By default, the job manager and worker services run as the user who starts

them. You can run the services as a different user with the following settings

in the mdce_def Þle.

Parameter Description

MDCEUSER

Set this parameter to run the mdce services as a user

different from the user who starts the service. On a

UNIX operating system, set the value before starting

the service; on a Windows operating system, set it

before installing the service.

MDCEPASS

On a Windows operating system, set this parameter

to specify the password for the user identiÞed in the

MDCEUSER parameter; otherwise, the system prompts

you for the password when the service is installed.

On UNIX operating systems, MDCEUSER requires that the current machine

has the sudo utility installed, and that the current user be allowed to use

sudo to execute commands as the user identiÞed by MDCEUSER. For further

information, refer to your system documentation on the sudo and sudoers

utilities (for example, man sudo and man sudoers).

On Windows operating systems, when executing the mdce start script,

the user deÞned by MDCEUSER must be listed among those who can log

on as a service. To see the list of valid users, select the Windows menu

Start > Settings > Control Panel. Double-click Administrative Tools,

then Local Security Policy. In the tree, select User Rights Assignment,

then in the right pane, double-click Log on as a service. This dialog box

must list the user deÞned for MDCEUSER in your mdce_def.bat Þle. If not,

you can add the user to this dialog box according to the instructions in

the mdce_def.bat Þle, or when running mdce start, you can use another

mdce_def.bat Þle that speciÞes a listed user.
